Bug 286919

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop i686
Distribution: "openSUSE 12.1 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I tried to add a Default Panel as the original one is not there
Shutdown the system and booted in failsafe mode, same issue
- Unusual behavior I noticed:
Information popups, context menus etc. do not disappear after a little while, desktop gets crowded with unused windows that are not active

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
